BounceBlock vs Spreadsheets
Cleaning a list by hand in a spreadsheet feels free, but it can't actually tell you whether an address is deliverable or a number is connected — it only sees text. It also misses duplicates that differ by formatting. Automated verification does in minutes what manual review can't do at all.
